PERPETUAL CALENDAR FOR WRITING INSTRUMENTS Filed April 8, 1933 Patented Sept. 5, 1933 PERPETUAL CALENDAR FOR WRITING INSTRUMENTS Joseph Moll, Philadelphia, Pa. Application April 8, 1933. Serial No. 665,054

Claims.

My invention relates to new and useful improvements in a perpetual calendar for writing instruments, and has for one of its objects to provide a perpetual calendar for use in connection 5 with a writing instrumentality, such as an ordinary pen, pencil, fountain pen or the like.

Another object of the invention is to provide a simple, durable, eflicient and handy device of this character wherein the writing instrumentality forms a part of the calendar mechanism which latter is adjustable so as to constitute a perpetual calendar, particularly adapted for indicating days and dates of certain years, for use as a memorandum to remind a person of some special day or date because of some particular event, such as historical and memorial dates, birthdays or when certain bills, insurance premiums and the'like are due.

A further object of the invention is to provide a calendar of unique construction embodying two calendar strips each connected with a pair of shafts carrying gears which are selectively rotatable by a pinion engageable with either of the pairs of shaft gears.

A further object of the invention is to construct the basic calendar mechanism in the form of a capsule for insertion in a hollow supporting member, such as the hollow stem of a pen, pencil or the like, or a cap to be mounted upon an article, such as a pen or pencil.

A still further object of the invention is to providev a pointer carried by the supportingmember for particularly indicating any particular date under a particular day.

Still another object of the invention is to pro- .vide a supplementary chart for use in connection with the calendar whereby aperson is able to find any day and date of the twentieth century which will be indicated on the calendar.

' With these and other ends in view, this invention. consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application, in which:-

Fig. 1 is a View of a writing instrumentality examplified as a fountain pen illustrating a calendar embodying my invention applied thereto.

Fig. 2 is an enlarged vertical sectional view of the fountain pen cap showing part of the calres PATENT oFFicE endar mechanism therein, the-calendar strips being removed for sake of clearness.

Fig. 3 is an outer or upper end View of Fig. 2.

Fig. i is a section on the line 4-4 of Fig. 2.

Fig. 5 is a section on the line 55 of Fig. 2.

Fig. 6 is a View of thechart used as a supplement to the calendar.

In carrying out my invention as herein embodied, 10 repres ents apart of a writing instrument which for purposes of illustration is shown herein as a fountain pen, and 11 is another part of a writing instrument, for instance a cap to cover either end of the part 10. While I have particularly illustrated the calendar in connection with a fountain pen, I do not limit myself to such use as it may be embodied in other articles or manufactured as separate'units, incapsule form to be assembled in or on any suitable supporting device.

The part 11 or cap window running has a long opening 12 or longitudinally thereof, and a small opening 13 or second window in endwise spaced relation to the long one. The openings may have sheets posed across the same.

of transparent material 14 dis- Where said part is a fountain pen cap, an end thereof maybe internally threaded as at 15 for connection to the part 10.

Adjacent the opening 6 for movement lengthwise of said a pointer 1 '12 is slidably mounted opening, the purpose of which will bepresently explained. By way of illustration,

I have shown this pointer as provided with a body 1'7 fitted in a dove-tailed slot 18 contiguous to the opening 12 and substantially of the same length.

Inside of the part 11 is fitted a casingor capsule 19 including body walls 20, a bottom wall 21, a top'wall 22 and at least two partitions 23 and 24. In the bottom wall 21 and the partition 24 are journalled 25 and 26, and on a pair of spaced parallel shafts the upper ends of said shafts fixed to their lower ends below the partition 23.

In other words, both sets of gears are located in thespace between the partitions 23 and 24.

A guide post 33 is located between the gears of both pairs, and mountedto rotate andslide on said post is a hollow sleeve shaft 34 having a knob 35 on its uppe'r end outside of the top wall 22, and a clutch pinion 36 on its lower end wh h th e sin is mo nt s a s en e lustrated in Fig, ,6.

for selective engagement with either gears. 7

To the shafts 25 and 26 are fixed the ends of a flexible date calendar strip 37 having day designations and dates therefor delineated thereon in a columnar form so as to be wound back and forth from one shaft to the other. Likewise,

pair of a monthly calendar strip 38 havingthe months movably mounted a top 4 1 which is a dial $2 I carrying a magnetic needle 43 constituting a compass which is visible through a transparent ane -.Q en. 4: ea n by th nto h A cork disc 'or' bloek 15 is assembled in the part 11 ,beloyv'the capsuleor casing'to prevent any leakage of ink from reaching the calendar j ement -j 1 If found ,desirable, the casing 19 may be made of two semi-cylindrical partsand the end walls and partitions with the other mechanism assembled in onelo'f said semi-cylindrical parts and th n h eth sem nd i a p t, placed in position and fastened in any suitable manner so that the resultant ,casingstructure ,will be cylindrical as herein shown and described.

A, chart or index card 46 may be provided as asupplement of the calendar to permit a person who .desires to find any date and day in any he h 0 le iye dur n th w ntieth c ur ,to' determin'e whicncol mn of dates must be turned into view through the openinglz in the part 1 1 of the writing instrument; I he,direchon in t eeha tte i xleeh h ed a an elem .efs id c art wh h is Y rieus .[e ihe s in f m r ort on, an -m Lh r eta ma he re o e t without ac ifi ing themany advantages of this invention, andof U TS I 5 0 no w hlto he l mit dt h exact details of construction as these. may be yaried with ut, departm f m t e spi it o m in e tion. r Haring th fu l d r b my i e t n What Iclai nas new and useful is:- "j A, 1.
